The concussion is massive, but we do this sort of thing outdoors. Inside on an indoor range and dust & crap falls from the ceiling and small creatures pack their crap and find another building's foundation to live in.

The wife and I both laughed at this. Yeah outdoors would not be to bad. I will have to pick a time when no one else is on the range to try. Though people are intrigued and want to come down and talk to you about either piece, a lot of people give you the old stink eye.
